The steps to remove the vertical air conditioner in winter are as follows:
Recover refrigerant. Start the air conditioner, set the refrigeration state, wait for the compressor to run for 5-10 minutes, after the refrigeration state is normal, use a wrench to unscrew the cap on the liquid pipe and gas pipe interface of the external machine, close the cut-off valve of the high pressure pipe (thin), 1 minute after the surface of the pipe condensation, immediately close the low pressure pipe (thick) cut-off valve, and quickly shut down, unplug the power plug, tighten the safety cap with a wrench, At this point, the refrigerant recovery work is completed.
Remove the indoor unit. After the refrigerant is recovered, the indoor unit can be removed. Use a wrench to unscrew the lock of the indoor unit connection, and use the prepared sealing sodium to screw the silk grain protecting the indoor unit connection joint; Then use the cross to remove the control wire.
At the same time, it should be marked to avoid incorrect connection during installation. If the signal line or power line is connected incorrectly, it will cause the external machine to not operate, or the machine is not controlled. The inner machine hanging plate is generally fixed firmly, and it is difficult to unload; After unloading, remove the hanging plate, place it on the flat cement floor, gently pat it flat and correct it.
Remove the outdoor unit. The outdoor unit should be dismantled by a professional refrigeration maintenance worker under the condition of ensuring safety. After unscrewing the connecting lock of the outer machine, apply the prepared sealing sodium particle to screw the silk grain of the connecting joint of the outer machine. Then use a wrench to loosen the fixing screws of the foot of the outer machine. When putting down the outdoor unit after disassembly, it is best to hang it with a rope. When unloading, pay attention to balance, avoid vibration and bump, and pay attention to safety.
Winter disassembly and installation of air conditioners need to pay attention to warmth and steps.
First of all, you need to turn off the air conditioning power to avoid electric shock.
Then, use warm measures, such as wearing cotton clothes, wearing gloves, etc., to prevent irritation by cold air.
Then, start from the shell of the air conditioner to disassemble, first remove the support of the air conditioner, and then remove the air conditioner itself from the fixing plate. During the disassembly process, you need to put it gently to avoid damaging the internal parts of the air conditioner.
Finally, the removed air conditioning parts are cleaned and stored for next use.
